Flooding, mold and chance for recuring flooding

Our Basement apartment was flooded two weeks ago. nor us or the landloard had flood insurance. We lost half of our things to the water. He has been working on the apt so we can get back in by tomorrow. The apt looks nice but the smell of mold is in the air. " its in the walls"  Also the reason why it flooded has not been corrected because he dosenot have the cash to do so.. He put us up at a hotel for the last 15 days but will not pay for another day… I want to know my rights about the situation… Is it leagal for him to fix the apt with out removing all the mold 100 percent. Also is it legal for him to leave the cause of the flooding unaddressed…

 thanks
